In this chapter Jesus focus on not following tradition. Sin begins in the mind from it comes the actions. God is interested in our heart and attitude.
We are saved individually and not by group. You are not saved by what religious group you are in.
For the believer there is no neutral either you're with God or against it.
Though we are doomed to hell God left his throne to become human (Jesus Christ) to die for our sins and save us. All we have to do is to accept the fact we are not perfect and have sinned against God.
John 16:7-8 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you. When he comes, he will prove the world to be in the wrong about sin and righteousness and judgment:
James 5:16 (NIV)
Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.
Feed your Holy Spirit so it will become strong.
2 Chronicles 19:9 He gave them these orders: “You must serve faithfully and wholeheartedly in the fear of the LORD.
For me this is one of toughest statement in the word of God. In this chapter during our Midweek Bible study, our theme was: "Serve Faithfully". It means to be fully committed and dedicated so we must have an undivided heart. And to act only out of fear of God not men because to fear/respect God = this is one of the keys to be able to serve Him faithfully.
